MEANS FOR DISPENSING LENS-CLEANING CLOTHS.

Application filed April 2, 1926. Serial No. 99,228.

The object of our invention is the provision of simple but effective means whereby a single lens cleaning cloth especially adapted to the cleaning and polishing of eyeglass and spectacle lenses may be positively, conveniently and expeditiously separated from the bottom of a pile of such cloths contained in a suitable receptacle, and rendered available for immediate use as hereinafter fully set forth, the invention consisting in the specific construction, combination and arrangement of parts described and claimed, whereby these and other advantageous results are attained.

In the accompanying drawings we illustrate a practical embodiment of the essential features of our invention as incorporated in apparatus for the storage, segregation and delivery of lens cleaning and polishing cloths of the character designated, although we do not limit ourselves to the identical form and construction of component parts shown by way of exemplilication, since changes may be made in minor details, and equivalent mechanical expedients resorted to with like results, and without departing from the spirit and intent of our invention in this re spect.

VJith this understanding Fig. 1, represents an isometrical View of our cloth dispenser, the cover being broken away in part;

Fig. 13, is a view of the cloth detachment plate;

Fig. 14., is a perspective view of the serrated starter frame; and

Fig. 15, is a perspective view indicating a form of lens cleaning cloth adapted for use in our dispensing apparatus.

The casing C, of our dispenser is rectangular in general configuration, its upper portion being formed with a transverse partition C, separating the cloth compartment C from the rear compartment G in which the release plate Fe, is located, the space be low said compartments C, C being for the accommodation of the other operative parts of the device. C is a cover plate for the exclusion of dust and extraneous objects.

The detachment plate D, is slidably supported between guide ways 0, 0, on the sides of the casing C, and isheld normally in retracted position by stops 6, (Z, on its underside contacting With shoulders o, c, at the front of the casing, by means of retractile springs a, a, attached to a cross bar at, on the underside of the detachment plate D, and to fixed points 0 0 on the inner side walls of the casing C, as shown more particularly in Figs. 2 and 3, of the drawings,-said cross bar d, being mounted upon and between brackets (Z (Z and said cross bar cl, also'functioning as the pivotal support for the starter frame S.

A shoulder (F, on the forward part of the detachment plate D, limits the inward thrust of said plate D, by contacting with the front walls of the cloth compartment (1. Said detachment plate D, is formed with a medial transverse delivery slot (Z for the accommodation of the tooth bar 8, of the starter frame S, said tooth bar 8, being rigidly attached to the side members .9, s, of said frame S, as shown more particularly in Fig. 14, of the drawings, and said side members 8, a, being extended rearward beyond the pivotal rod cl, of the frame, to constitute trip arms s 8 which, by condetail taken upon tacting with'fixedtrip shoulders 0 on the lower edge of the partition 0, rock said starter frame S, forward and upward with its tooth bar a, protruding into said transverse slot d in the detachment plate D.

The front edges of the lowest cleaning cloth is, to be dispensed est upon a series of spaced apart shoulders 0, 0*, on the lower edge of the front wall of the cloth compartment C the spaces between said shoulders c, 0 being for the accon'nnodation of the teeth of the bar s, o-l the startertrame; and the rear edge oi said lower cleaning cloth 7c, of the pile thereof in the cloth Compartment Cflrests iipoirtlie ilorward edge 1', ot the releaseplate R, as shown more particularly in Fig. 11, 01 the drawings.

The release plate it, is attachedto and suspended upon a flat spring r, the upper end of which is ri "'lly secured to the partition C, said spring r, tendingnormally to hold the release plate R, in advanced position with its forward edge 9*, under. the rear edge of the lowest cleaning cloth L, as before stated. In this position shoulders r 7 on up release plate R, rest against the lower edg e ot the partition C, and thus limit the forward thrust of said release plate, as shown in Figs. 2 and 10.

f, f, are twin spring stripping fingers mounted on the forward end of a bracket F, attached to the rear wall C, of the casing, C, below the release plate R, and below the path of the detaclnnent normal position of these stripping fingers e; when the operative parts are at rest) is shown'in Fig. 4, During the rearward thrust oi the detachment plate D, pin did, on the underside of the latter contact with saidstripper lingers f, and force them back into the positions indicated in Fig. 5, just prior to the completion of said rearward thrust ot the detachment plate D, but thecompletion of StilllllOVGl'IlQIlt carries the (Z beyond the ends of said stripper pins kl, fingers f, 7, so that the latter then'autoinatically spring forward and impinge against the portion of the cloth is, adjacent to and protruding through the slot (Z as illustrated in Fig. 8, of the drawings,the kiclid thus administered insuring the detachment of the rear edge of the cloth it, from the liront edge r, of the release plate It, and from the layer of cloths above, and thus preventingclogging.

Preferably a follower weight W, is placed upon the topof the pile of lens cleaning cloths 76, deposited in the containing compartment Cf, as indicated in Figs. 2 and 3, ot' the drawings. I

Presuming the operative parts to be in normal relative positions, as in Figs. 2, l, 10 and 11, at. the inceptionot the rearward movement of the detachment plate D, under plate D. The

hand pressure applied to the protuberant front portion thereof, the teeth on the bar s, of the starter frame S, cause the front edge of the lower cloth. Z2, to assume a partial told, as indicated at In, Fig. 6, sufficient to cause said front edge of the cloth to clear the shoulders 0 onthe front wall of the container C Next, as the rear movement of the detachment plate D, is continued, the trip armss 8 on the starter frame S, clear the trip shoulders 0 on the lower rear portion oi the partition C, thereby allowing the starter frame S', to turn by gravity on its pivotal supportd", the first result being" indicated in hig. 7, which shows the drop of the front-end of the cloth through the transverse slot- (Z, in the detachment plate D. As the rearward movement progresses the pins (Z (/7, on the under side ot the detachment plate D, engage with and push back the stripper lingers f, and said detachment plate D, also contacts with the shoulders r on the rear edge of the release plateR, thereby retracting the same against the resistance of the suspe'nder spring r, and withdrawing the front edge 0', of said release plate R, from beneath the rear edge of the cloth is, and simultaneously releasing the stripper fingers f, f, and cansinpthem to impinge against the rear edge or the cloth 7s, as indicated in Fig. 8, to insure clearance thereo'lif Upon the release of the detachment plate D, from hand pressure,the retractile springs a, a, return all the op'erative parts to normal positions, ready for the dispensing of the next succeeding cloth 70, at the bottom or the pile thereof in" the container C It is to be understood that the lens cleaning and polishing cloths 7c, are designed primarily for gratuitous distribution by opticians and others interested in the trade, and to function as advertising mediums.
